I'm not sure if this is a video card issue (AMD Radeon HD 6770), driver issue or monitor issue. I just rebuilt my system (Win7 Pro 64 bit) and everything has been functioning correctly for about two day. Now, when my computer resumes from sleep mode, my resolution defaults to 600 x 800 and says it is a generic PnP monitor. If I unplug the display port cable from the back of the computer and plug it back in, everything immediately goes back to normal and the system recognizes my monitor and goes to the correct resolution settings. This does not happen on a restart or after a shutdown, only after a resume from sleep mode and about 60% of the time. This never occurred before the rebuild so I am wondering if I have a driver conflict somewhere? I changed the setting in the monitor from auto to display port, but that did not change anything. I have been using the display port connection since I got the monitor without issue. All of my Windows updates and drivers are up-to-date and the driver version for my video card say 8.960.0.0, March 15/12.

I uninstalled and reinstalled the monitor driver. So far all is well with resuming from sleep mode. I have a paid subscription to a driver program so I know all my drivers are up to date. This problem just started happening after I reinstalled my OS last week so I think I was dealing with a driver confict.

"Paid subscriptions" to driver update software can be dangerous. You should only upgrade/install drivers based upon your needs. Most complaints that we see, relative to drivers, are due to automatically updating, or unnecessarily updating.

Hey James, thanks for the info. I've used the driver program for a few years now and have not had any weird issues (other than this one) that I can recall. The program has also been good at finding missing drivers when Windows cannot locate them, mainly on XP machines. Windows 7 does a great job of finding and installing drivers. Seeing as the problem began after I reloaded the OS a week ago, I suspect a bad driver somewhere is causing the issue. I may blow it all away and start from scratch this weekend as the problem still persists. First I will remove the video card and try the onboard video to see if it is something to do with the video card driver.

Monitor and sleep modeI would like my monitor to stay on all the time. I have set all the area's that I can find to leave the monitor on in W7. But after 15mins. the monitor will turn off. Is there a area that I might have missed? Thanks!

General Discussion

Monitor sleep mode?When Windows 7 puts my PC into the sleep mode & my Acer LCD monitor goes black, is the monitor actually powering down the lamps or is the PC just not sending it a signal to display?

Hardware & Devices

Monitor goes into sleep mode when set to neverAll settings are set to never allow the monitor to go into sleep mode but it does. I am quite sure it is the computer that is doing it as I can move the mouse and it comes back on.I think there are settings in the bios that need to be changed, but i don't know which ones. I have an Phoenix Award...

Sleep constantly resumesI keep hoping that my problem will be resolved in each build, but no.
What happens is that when I put my PC to sleep, it happily does that. Everything switches off correctly.
But, a few seconds later, it wakes up and goes into the login screen.
Works perfectly OK in Vista.
Anyone any ideas? ...
